هههه عنوان الموضوع مو متناسب مع الطرح
بس لازم اعمل كذا عشان تناظرون سؤالي .....والآن
السسسسسسسلام عليكم
اخواني 00اخواتي
عندي سؤالين اريد الأجابة عليها
ممكن افادتي ولكم جزيل الشكر ...
The position of a particle moving along the x axis is given by , where x is in meters and t in seconds. What is the position of the particle when it achieves its maximum speed in the positive x direction?
السؤال الثاني :
A particle starts from the origin at t = 0 with a velocity of 6.0i m/s and moves in the xy plane with a constant acceleration of (–2.0i + 4.0j) m/s2. At the instant the particle achieves its maximum positive x coordinate, how far is it from the origin?
